MIPS: Kernel: Add relocate.c
arch/mips/kernel/relocate.c contains the functions necessary to relocate
the kernel elsewhere in memory
The kernel makes a copy of itself at the new address. It uses the
relocation table inserted by the relocs tool to fix symbol references
within the new image.
If copy/relocation is sucessful then the entry point of the new kernel
is returned, otherwise fall back to starting the kernel in place.
